Cold pressure. Poor water flow: no water pressure in the riser

Dissatisfaction with the pressure of water in the system is a domestic problem that affects everyone, regardless of where they live (an apartment or a separate building) and property rights. Water supply in private houses is organized either from offline source, or connection to the central highway.

Consider everything possible ways increasing the pressure in the circuit, and the reader himself will determine what exactly needs to be done in relation to his home. Moreover, most issues are resolved without any impressive material costs.

It will not be possible to increase the pressure in the pipes () without knowing what caused the decrease in pressure in the water supply of a private house. This is where you need to start solving the problem. It is impossible to take into account literally everything, but there are a number of typical, most common “malfunctions” that you should be aware of.

Leaks, accidents on the highway.
Decreased Dy pipes due to foreign deposits on the inner walls of the water supply sections.
Clogged cleaning filter at the entrance to a private house.
Defects (faults) stop valves.

If the water supply of a private house is centralized, then possible reason decrease in pressure in the system may be due to poor quality work of the supplier (for example, turning off one of the pumps at the substation in order to save electricity, an accident on the highway). Before thinking about ways to increase pressure, you should ask the owners of adjacent buildings if they are experiencing difficulties with water supply.

If this is a common problem, then first of all you need to “pull” the public utilities. The basis is the provisions of SNiP No. 2.04.02 of 1984, government decree No. 307 of 2006. The minimum pressure on the supply to a private house (for a one-story building) is 1 bar. If there is a 2nd floor - already 2.4.

In order not to run around the neighbors, it is advisable to put a control and measuring device (pressure gauge) on the "thread" between the well and the house. At least, it will immediately be clear where to look for the cause - inside the home or outside it.

What to check first

The author will only present an algorithm of actions, his vision of how to solve the problem of increasing pressure more easily. And what exactly should be done, the reader will understand for himself. We proceed from the fact that if the house is connected to the central highway, and there are no complaints about the public utilities, the water is supplied with the proper pressure.

Checking the performance of the pumping station

There is nothing complicated here, since it contains a pressure gauge showing the pressure at the entrance to the house. If the pressure is below the nominal value, you will have to do unscheduled maintenance of the pumping "economy". Usually the most probable cause– clogged depth filter. When a set of equipment is assembled by hand, the task is simplified. The owner (he is also a master) himself knows all the weak points.

Monitoring the condition of the fine filter

Usually refers to the product at the entrance to the building. Often, it’s just that “hands don’t reach it”. Even less often, owners pay attention to individual, which must be placed on the line of connection to the water supply of each of household appliances. If the same washing machine does not work well, this does not indicate a decrease in pressure in the system.

Pressure check at all points

You should go around the house and check how the water flows from each tap. It is one thing when, when all the valves are fully opened, only a weak stream appears from them. The reason is clear - the problem is in the central pipe. Plot - from pumping station to the distribution point for the premises. The case is extremely rare, especially when not "hardware" was used during the installation of the water supply system, but.

Another typical cause is a leak in the circuit. Only a significant defect has a strong influence on the pressure, and such a place is easy to determine visually. If not a puddle, then a wet spot will appear on the ground - for sure.

Insufficient pressure from only one tap narrows the troubleshooting sector. Firstly, it is necessary to examine that part of the house along which there is a “thread” for supplying water to this valve. The task is the same - to check for puddles on the floor. Secondly, if everything is normal, disassemble the faucet and determine what the problem is. Nothing else can be.

Ways to artificially increase pressure

Inclusion in the circuit of an additional pump

The pump is selected individually for each plumbing system. A number of its parameters are taken into account - the length of the highway, the cross section of pipes, the number of storeys of the house, and the like. This is a separate topic for consideration. But in terms of recommendations, we can advise such models as the Russian "Comfort", imported "Grundfos", "UNIPUMP". They showed themselves well in practice, and the reviews of the owners of private houses about these pumps are the most favorable.

What to look for when choosing a pump

The price of the product is at the discretion of the reader. From the point of view of the expediency of the acquisition, you need to familiarize yourself with the three main characteristics of the pump.

Productivity (l/min).
Head (m).
Power, W).

It remains only to add that such an acquisition is not too burdensome. Price household pumps of this class within 6,900 - 8,450 rubles (depending on the characteristics). In principle, you can get by with cheaper products, since we are talking not about pumping water from a source (well, well) to the house, but only to raise its pressure.

There is a category of products - "booster pumps". For a private house, which necessarily has some kind of equipment connected to the water supply, such models (despite the attractive cost) are not suitable. There are several arguments (for example, when starting washing machine you will have to open and hold in this position all the time while it is working, 1 - 2 taps), but believe me, reader, for a word - there will be problems, and such a device will not serve for a long time.

Partial alteration of the water supply system

In the private sector, "doing it all on your own" is welcomed. This is fully justified, but not where competent engineering calculations are required. When installing a water supply system, someone focuses on neighbors, for someone "authority" - articles and tips from the Internet.

What can cause a decrease in pressure? Even if everything is normal, one of the reasons is the incorrect determination of the diameter of the line. The pipe itself "steals" the pressure. Plus, there are turns on the track, valves, fittings, expansion / contraction, and the like.

If no other ways to increase the pressure help, it makes sense to invite a specialist. Perhaps the solution to the problem lies in the modernization of the track.

Installing a hydraulic accumulator

In the case when it was not provided in a self-mounted system, it can solve the problem low pressure. As an option, replace it with another if the one used was incorrectly selected initially. By the way, the larger the volume of the tank, the less the pump is in operation. Consequently, its service life is increased.

Low pressure is not only an inconvenience in using plumbing. Weak pressure adversely affects the operation of some household appliances, and is often the cause of their rapid failure. The value of this parameter should be constantly monitored. For what? Even if household members do not particularly experience discomfort from pressure reduction (or do not pay attention to it), then complex equipment sometimes “reacts” very painfully.

Determine the range of devices, the operation of which is somehow connected with the plumbing system (washing and dishwasher, heating boiler, and so on).
View their passports and write out the values of the minimum pressure at which the unit can function normally. The critical value (lower level) of water pressure in relation to your home will immediately become clear. If a control device shows a smaller one, but this does not interfere with the residents, after all, it is worth taking care of the problem of increasing the pressure. At least, zealous owners should do just that.

It is worth recalling that one of the reasons for the automatic termination of the manufacturer's warranty obligations for new equipment is a violation of the conditions for its operation. In this case, the mismatch between the parameters of the water supply system and the nominal working pressure indicated in the product passport. For those who, for some reason, do not have at hand required document, the author suggests.

The minimum values of water pressure (bar) in the pipes suitable for the devices, at which the equipment can function normally, are:

jacuzzi - 4;
most boilers - 2.5;
machine (washing) - automatic - 2.

If water comes out of the showerhead, this is not yet an indicator of sufficient pressure in the circuit, since the mixer also works at 1.5 bar.

Even if the pressure in the water supply does not drop below the “critical” level, it is worth considering whether two simultaneously turned on “consumers” of water can work normally. For example, a boiler and a shower. After all, taking procedures in the bathroom, the owner cannot control how stable the heat generator works. Therefore, when checking the pressure, you need to “activate” something (open a couple of taps, for example). Especially in summer when the heating is turned off. Data measuring instrument will be more objective.

As well as a small, excessive pressure in the water supply will cause a number of problems. For example, not all pipe connections can withstand such a load. Therefore, you should not get carried away by raising the face value. This is not the case when “the more the better”.

A weak pressure in the water supply can "please" the owners initially. This often happens in a new private house, when everything is mounted from scratch. And, as in most cases, with their own hands. The most likely reason for the reduced pressure is the wrong choice of model or calculation of its parameters at self assembly equipment from individual components.

In the sector of intensive development, "surprises" of electricity supply are commonplace. A lower voltage rating leads to a deterioration in the operation of the pump, hence the decrease in pressure in the water supply.

Information "for reflection" in abundance. The article is more than detailed, and the author hopes that the reader will definitely learn at least something useful from it.

For the smooth functioning of plumbing fixtures, it is necessary that the water pressure in the water supply system correspond to a certain indicator, which is usually calculated individually.

But correct calculations do not guarantee that in practice the water pressure will be optimal. Owners country houses most often faced with the problem of low water pressure in the pipes. It can be solved by introducing equipment.

We propose to figure out what are the pressure standards in the water supply of a private house and for what reasons the pressure decreases. We will offer effective methods improving the efficiency of water supply. We added material detailed photos instructions and videos.

Residents of private houses are forced to calculate the pressure in the water supply individually. If the system is autonomous, the pressure may exceed the allowable regulatory documents borders. It can fluctuate around 2.5-7.5 bar, and sometimes reach 10 bar.

The standard values \u200b\u200bfor the normal operation of the system with are considered to be an interval of 1.4 - 2.8 bar, corresponding to the factory setting of the pressure switch indicators.

If excessively high pressure is provided in the system, then some sensitive devices may fail or work incorrectly. Therefore, the pressure in the pipeline must not exceed 6.5 bar.

High pressure in the water supply can cause the pipe to leak, so it is important to pre-calculate the optimal pressure level yourself

Gushing artesian wells are capable of delivering a pressure of 10 bar. Only welded joints can withstand such pressure, while most fittings and shut-off and control units are destroyed under its action, resulting in leaks in the areas.

It is necessary to determine what water pressure is necessary for the normal functioning of the water supply system of a country house, taking into account the household appliances used. Some types of plumbing fixtures do not work at low pressure.

For example, for a jacuzzi, a pressure of 4 bar is required, for a shower, fire extinguishing systems - 1.5 bar, for a washing machine - 2 bar. If you provide for the possibility of watering the lawn, then there should be a strong pressure of 4, sometimes 6 bar.

Household plumbing fixtures connected to the water supply are able to work correctly only from a certain pressure, which is usually at least 1.5 bar

The optimal pressure indicator for a country house is 4 bar. This pressure is enough for the proper operation of all plumbing devices. At the same time, most fittings, shut-off and control valves are able to withstand it.

Not every system can provide a pressure of 4 bar. Typically, for country houses, the pressure in the water supply is 1-1.5 bar, which corresponds to gravity.

Causes of low pressure in water supply

AT country houses water in the water supply network comes from or.

If the system is completely autonomous, then two points must be taken into account to create the desired pressure:

the need to ensure the rise of water;
it is important to make a correct hydraulic calculation and implement it correctly in practice - to ensure the necessary pressure at points remote from the catchment area and at points located at different heights.

Two main problems of individual water pipes follow from this:

Not enough well resources- the flow rate of the hole does not allow maintaining normal pressure, and, consequently, increasing the pressure.
Plenty of water in the well, so the pumps can pump high pressure (up to 6 bar), which can lead to broken connections, leaks, and rapid equipment wear.

In the first case, pumps pump liquid, creating its circulation until a certain pressure arises, but over time it weakens. In the second case, you need to choose a pump with a capacity that is equal to daily rate water consumption.

The flow rate of the well directly affects the pressure of water in the pipeline and its volume supplied for one pumping

However, most owners of private houses are concerned about the question of how to competently increase the pressure in their own water supply, and not lower it, because the necessary debit to create high pressure possess only some artesian wells.

Most of the holes generate weak pressure water, or even not able to produce any pressure at all.

If standard household appliances are used in the house, then it is enough to raise the pressure to 2.3-2.5 bar - this wave is enough for their uninterrupted simultaneous functioning with good pressure. If a jacuzzi or irrigation system is provided, then higher pressure is needed.

A manometer is used to measure pressure. It is bought separately and built in at the point of entry of water into the house. A water meter is also installed there. Some equipment comes with a pressure gauge. For example, a heating boiler, if a FGP is provided.

The principle of pressure regulation of water supply networks of private houses is the same as that of an autonomous system, the network differs only in size

A simple pressure gauge has a scale from 0 to 7, which allows you to install it in an apartment, a private house.

Methods for pressurizing the system

If the pressure in the water supply is low, then the reason may be as follows:

There is water in the pipeline, but there is no pressure.
There is no water in the pipeline on the upper floors.

To solve the first problem, it is necessary to introduce a pressure booster into the system; to solve the second, install a storage station.

Before implementing technical means into the water supply system, you should first check the network for clogging:

#1: Introducing a booster pump

If water is present in the pipeline, but there is no pressure, then a pressure pump is installed. Also, the device can be implemented if there is no pressure in an apartment with central heating.

The reason for the lack of pressure may be the following:

the well is located remotely at home;
the power of the base pump is not enough to supply water to the upper floors.

The pump is usually mounted at the entrance to the domestic pipeline network in front of the manifold or the first tee.

There is one disadvantage of central pumps - they create a vacuum, that is, they can pump air-saturated water. A conventional positive displacement centrifugal pump is sensitive to the air content in the liquid, so vibration modifications should be preferred.

The water pump is powered by an electric motor. The inner element rotates, thereby increasing the pressure in the pipes. The body of the device is usually made of durable plastic.

To install the device in apartment building it is important to choose a modification of the correct power, otherwise the owner of the “pumped” water supply will lower the pressure in neighboring apartments. It is recommended to put the pump on a pipe leading to a specific household appliance.

In general, the pump is embedded in common pipe, which is responsible for supplying water to an apartment or house. The device itself is quite compact and inexpensive.

#2: The main types of pressure pumps

There are models with a dry and wet rotor (flow-through). The wet rotor pump elements are lubricated by the passing fluid. Devices of this class do not require additional maintenance if they are initially connected correctly.

An electric pump, unlike a vibration one, is installed between the water supply and the water source

A pump with a dry rotor has good power, but it needs regular maintenance, it produces soft sounds during operation, reminiscent of a mosquito squeak. Its parts are protected by a waterproof damper, so you will have to clean the device once a month.

According to the type of operation, pumps are divided into the following types:

manual booster pump and with manual control. The model constantly works, has no automatic switches. The device has a simple design that is understandable to ordinary people; most often the device is used in "warm floor" systems;
automatic pump- starts only when you turn on the tap or household appliances. After they are closed, it turns off.

An automatic pump is more expensive than a manual one, consumes little energy, quickly responds to changes in pressure and is the most popular today.

Choosing a pressure pump is quite simple.

It is important to determine the following:

the device will be installed on hot or cold water;
the required level of pressure - the higher the indicator, the greater the pressure in the system.

Accordingly, the higher the pressure, the more power is needed and bandwidth equipment.

It is equally important to choose a pressure pump taking into account the brand, since in the event of a breakdown, not every repair service will undertake to put in order the production model of an unknown company. The most famous and recognized manufacturers - Grundfos, Wilo, Sprut. Each firm specializes in the production different modifications device.

The Wilo PB-401SEA pump is designed to increase the pressure in water networks housing sector. Can be installed in both suction and delivery sections

For example, Grundfos produces circulation pumps of small volume, Wilo develop models with a built-in hydraulic accumulator.

To connect the circulation pressure pump you need:

Turn off the water in the area.
Release water from the pipeline and the system as a whole.
Cut off the part of the pipe in which the installation will be carried out.
Attach fittings and nozzles to the joints.
Insert the equipment into the plumbing.

It is also acceptable to use polypropylene or rubber hose to simplify installation. In modern circulation pumps these pipes are included.

#3: Pressurizing the storage tank

When pipelines are without water in the house, or if water is present on the lower floor, but does not reach the upper ones, it is necessary to purchase a storage pumping station. It is also introduced into the system when the network pressure is less than 0.2 bar and the flow rate is less than 2 l/m.

Any pumping station works on the same principle. Mount it at the junction point of the external or internal branch of the home pipeline network

The principle of its work is the following. The pump pumps liquid into the station (tank or accumulator), which operates at a pressure of 1.5-2 bar. Water enters until a pressure of 1.5 or 2 bar appears in the tank. If the station is equipped generated pressure may be an order of magnitude higher.

After generating the required pressure, the pumping station switches off automatically.

Special pressure sensors are introduced into the design of the storage station. When the pressure drops to 1.5 bar, the main pump turns on, when it rises to a certain level, it turns off.

The system with a pump and a storage tank has many nodes, which makes it difficult to self-assembly. In order for the equipment to work correctly and smoothly, it is better to contact specialists (+)

The pump in the station can be one of two types - or vibration.

According to the type of absorption, there are:

detachable ejector designs– capable of generating a pressure of 5 bar. The ejector is immersed in the well, and the tank itself can be located at home, since it practically does not make noise during operation. The station is mainly used in cases where the water source is located deep, and its disadvantage is sensitivity to mechanical elements - sand, dirt, etc.
equipment with built-in ejector– suitable for shallow (up to 8 meters) wells and wells, works effectively in dirty water, not sensitive to air ingress, but different high level noise, so it is usually installed in special outbuildings.

Models with a storage tank are economical (the start occurs when the tank is empty), but they have many disadvantages: they generate low pressure, have large dimensions, there is a possibility of a rupture, as a result of which the room may flood.

Stations with a storage tank are practically not used today. They were replaced by models with a hydraulic accumulator. They possess small size, do not make noise during operation.

You can install the device in the basement, utility room, separate extension. This minimizes the risk of leaks. But the accumulator has a small capacity reserve (about 25 liters) and is not used for wells with a low flow rate.

Pumping stations are often used in complex, branched and long water pipelines as booster equipment that pumps water from storage tank at the water points

Stations are also divided into surface (when the pump is located on the ground) and submersible (the device is immersed in water), the latter are conditionally divided into well and borehole.

To increase the level of water pressure in the apartment pipeline, pumping stations are not used due to design features and noise during operation.

Despite its impressive cost, the pumping station has a number of undeniable advantages:

it is possible to set any desired pressure in the house, which will allow the use of any plumbing fixtures, including those that require high pressure to function;
the water supply will be uninterrupted even if it is absent in the central line (due to the presence of a storage tank).

The system has disadvantages - it is bulky, takes up a lot of space.

It is important to correctly determine the volume of storage capacity. This value is taken taking into account the average daily rate of water consumption. If the family consists of 3-4 people, then about 500 liters of water will be enough per day.

When calculating, it is also important to take into account that the water needs to be renewed from time to time in order to avoid the appearance of bacteria.

If there is enough water in the tank (or the pressure in the system drops), then the pump automatically starts, which builds up the necessary pressure in the network, and after reaching a certain point it turns off

It is important to clean the storage tank in a timely and regular manner, since pathogenic bacteria accumulate in it. Small bags of technical silver placed inside the tank prevent their reproduction.

It should be remembered that there should not be shutoff valves on the overflow pipe. If the float valve fails, then water will be drained through it.

It is also necessary to install a bypass so that in the event of a breakdown of the station it is possible to turn off the system without completely turning off the water supply.

Conclusions and useful video on the topic

Roller #1. How to choose a power station. In the video you can learn about the features of the choice power plant with hydraulic accumulator:

Roller #2. The video describes the main points when installing a pressure pump:

As you can see, it is not difficult to raise the pressure in the water supply. To solve the problem, a pressure pump or a special pumping station is used. If it is possible to carry out the installation of the pump on your own, then the installation of the station should be entrusted to professionals.

Water is supplied to the houses through a network of water pipes, the condition of which leaves much to be desired. Operating organizations are afraid of damaging worn pipes and periodically reduce the pressure in them by reducing the volume of passing water. At the same time, cold water from the taps begins to flow very weakly.

Sometimes the problem of low pressure cold water associated with clogging of risers throughout the house or with incorrect operation of water shut-off and control valves in basement. In some cases, there is a decrease in the passage opening of the water pipes located in the apartment, which naturally leads to a decrease in water pressure. Another reason for low cold water pressure is a clogged or faulty faucet.

What to do if there is a decrease in the pressure of cold water in a house or apartment

If a weak pressure is observed in only one plumbing fixture, and in other places of the apartment the water flows normally, then the problem may be a clogged pipe or a malfunction of the device. Clogging is likely if the plumbing fixture is at a great distance from the riser. If all other taps and appliances have good water pressure, the problem lies in the malfunction of one particular one. You can restore the normal water supply by replacing the plumbing fixture or removing the blockage.

With a weak pressure of water in all apartments in one riser, the cause should be sought either in the clogging of the riser, or in the operation of the main water supply. It may be necessary to replace the water riser in one or all entrances.

If a water riser needs to be replaced, it should be replaced as a whole, not in parts.

If a weak pressure is observed in only one apartment, you need to check the patency of the water pipes and the serviceability of the taps between the risers. The problem is solved by installing new pipes and repairing faucets.

The low level of water pressure in all risers of the house indicates problems with the main water supply.

You can increase the water pressure with the help of an electric pump, but at the same time, the pressure in the pipes of neighboring apartments will drop sharply.

In this case, residents should contact the housing office or the management company, because it is these organizations that provide paid utility services, the quality of which must meet certain standards.

Many users complain that the water pressure in the faucet is weak. If the cause of inadequate pressure depends on the owner of the premises, he is obliged to eliminate it independently. For example, it may be a clogged water filter. In this case, it is enough to clean the filters yourself and the pressure will be restored.

The filter can be installed directly in the riser, in which case its cleaning must be agreed with the ZHREU service. However, this reason is also easily eliminated.

Unfortunately, the most common reason for no water pressure on the riser, This corroded pipes, which leads to an automatic decrease in the water flow. Replacing water pipes in the apartment does not lead to positive result because the cause is external. Only the public service can deal with this. Replacing pipes is a very expensive and time-consuming undertaking. Many have been waging wars with housing departments for years in order to achieve at least overhaul plumbing.

If a the water supply riser itself becomes unusable, the repair of which is also imputed to the public service, it is easier for residents of one entrance to solve it. Residents of apartments using one riser calculate the cost of new pipes, purchase them and hire a worker for installation. This measure is cardinal, and the reason for the low pressure in the water supply can be just riser clogging. In this case, it is also cleaned with the help of specialists from the housing department.

Another reason that water does not go well is the valve that regulates the water supply to the house. It is located in a service room (substation, basement, boiler room), where there are pressure control devices in pipes and a public utility worker responsible for their readings. Faucet may be faulty, and if this malfunction is proven, it is only necessary to achieve the elimination of the breakdown. More global problem lack of sufficient pressure in the pipes can be almost fraudulent actions of housing department employees: the pressure is deliberately reduced to prevent the failure of obsolete water pipes, however, during any check, the pressure is correct.

Finally, with the start heating season happens often system airing central heating . If the water pipes are directly connected to the heating pipes, this can also serve to reduce the water pressure in the tap. The most important sign of such a situation is the incomplete heating of the radiators. Opening the faucet and letting air out until water appears in the battery by everyone associated with the problem riser should solve the problem.

In addition to knowing the water supply system of an apartment or house, the owner must know the laws, in particular "Rules for the provision utilities citizens” (approved by the Government of the Russian Federation No. 307 dated May 23, 2006), which regulate the actions of the consumer in a problem situation:

“In case of non-provision of public services or provision of public services of inadequate quality…. notify the emergency dispatch service "
“Report on the non-provision of utilities or the provision of utilities of inadequate quality .... subject to compulsory registration in the emergency dispatch service "

These actions serve as the basis for an official appeal to higher authorities and a solution to the problem of low pressure in the water supply.

Many owners have faced the problem of low water pressure in an apartment building. Low water pressure in the apartment not only creates domestic inconvenience, but also adversely affects the condition plumbing equipment. However, the fact of poor water supply does not in any way affect the cost of utilities - payments are still charged in in full. We will tell in the article why there may be a weak water pressure in the apartment and what to do in such a situation.

First of all, let's figure out what water pressure in the tap can be considered weak. The norm is calculated based on the rules provided for in SNiP 2.04.02-84. The maximum water pressure can be:

6 atm - for cold water supply;
4 atm - for hot.

At the same time, the minimum allowable values of water pressure for appliances are provided:

It's fast and for free! You can also quickly get a response through the consultant form on the site.

toilet bowls with flush cisterns - 0.2 atm;
sinks with mixers - 0.2 atm;
baths with mixers - 0.3 atm;
shower cabins with faucets - 0.3 atm.

A water pressure of 2 atm is considered sufficient. At lower pressure it becomes difficult to use domestic water, and if you find this, you need to solve the problem.

The main causes of low water pressure in the apartment.

The problem is in the main pipe. Water enters the apartment from the pumping station through the main pipe. Over time, it can become clogged or, simply, “serve its own”. To avoid the risk of pipe rupture, water supply companies reduce the pressure. There is only one solution to the problem - replacing the main pipe.
Construction of a new high-rise building. building residential building also implies the provision of its water supply, but at the same time additional pumping substations may not be installed. In this case, the water pressure, which was divided, for example, by five houses, will now be distributed among six. Accordingly, the water pressure in the apartments becomes less.
The problem is in the stands. Over time, risers, like main pipes, become dirty and age. If the problem of low pressure lies in them, a complete replacement of the equipment will be required. Partial replacement of the riser will not change anything.
Wear of locking equipment. The management company is obliged to control the condition of the valves in specific houses and entrances. She also replaces equipment when necessary.
The problem is in water pipes located in the apartment. The owner of the dwelling must monitor the condition of the pipes directly in the apartment. Call a plumber to check. Costs are borne by the owner, unless it is a public housing unit.
Wear of the mixer or clogging of the faucet box. Clogged, the axle box crane will not open at full capacity and will increase the load on the mixer. This leads to a decrease in water pressure. It will help to solve the problem by replacing the faucet box or mixer completely.

The exact reason why the tap has a weak water pressure can only be told to you by a specialist after carrying out the appropriate work.

How to increase the water pressure in the apartment?

First of all, we will tell you what can be done to increase the water pressure in the apartment on your own. Sometimes the problem is solved without involving management company and other authorities.

So, what can the owner do to increase the water pressure in the apartment?

First of all, check the valve that shuts off the water. Perhaps it was not completely unscrewed and therefore there is no water pressure in the apartment.
Cleaning or replacing the filter, faucets, hoses or pipes can help increase water pressure.
Poor water pressure can be corrected by installing an electric pump in the apartment. This will not increase the volume of water in the riser, but turning on the pump during water consumption will improve the pressure.
Sometimes the installation of pipes with an increased diameter helps to increase the water pressure in the apartment. This will reduce the resistance to flow and, as a result, increase the pressure.

Before purchasing optional equipment, pay attention to the age of the pipes and mixer in the apartment. Pipes wear out in 5 years, and a mixer in 2-3 years. Probably worth replacing them. If the supporting cranes are reliable and nothing threatens the general house water supply, you can do without involving a management company.

Poor water pressure in the apartment: where to go?

Water supply apartment building- a complex mechanism, it is controlled by several organizations. The management company is responsible for the supply of water inside the house. Hot water supplied through the heating plant. Cold water supply is Vodokanal's area of responsibility. The owner may have an agreement on the supply of water with the management company or with all of the listed authorities.

Often, when trying to solve the problem of poor water pressure, the owner is faced with the unwillingness of the management company to repair water supply networks. Then there is a situation when all the authorities responsible for water supply, without taking any measures, try to shift the responsibility onto each other.

How to increase the water pressure in the apartment and where to go? You need to prepare for a long interaction with utilities and be patient. However, the problem is solvable from the point of view of the law, so it does not hurt to contact a lawyer for advice.

The first thing to do is to report a weak water pressure in an apartment or house in writing. The application is made to the HOA or the management company. It states:

the presence of the fact of poor-quality performance of public services;
the requirement to recalculate payments for water supply for the entire period when the water pressure did not meet the norm;
a requirement to take corrective action and restore normal water pressure.

The complaint can be individual (signed by you personally) or collective (signed by all concerned residents of the building). Be sure to keep a copy of the application and require it to be registered immediately upon submission.

The maximum processing time for an application is one month. When the situation is an emergency, action must be taken immediately.

If the situation has not been corrected in a month and there has been no action on the part of the management company (it is obliged to report to the applicant orally or in writing about this), you should contact the higher authorities. In this case, it will be the administration department for housing and communal services. Attach a registered copy of the complaint to the management company to the application to the administration.
